nUMrrNG BODY.`

Application filed October 18,1927.` Serial No.` 22(5,989iA This inventionrelates to `dumping bodies and more particularly tothe construction of a dumping body for motor trucks and the like, of such character that the body is tilted and during the tilting operation is forced longitudinally, so that itmay be extended well beyond the rear end of the chassis frame to dc- .n

and shifting ineanswith the gearing being such thatthe tilting means` is continuously operated while the `shifting means isliiiterniittent in its operation, being at first inopei' ative to permit the body to be tilted to a position where it clears alleobstructions, then operating `to shift the body longitudinally to a properdumping position and then again be i comes inactive to perniit` the completion of the tilting movement. y i

A still further object of the invention is to provide a construction such that during trans portation, the body is very firmly locked in position and held against vibration. Astill further object ofthe invention is to provide a device of this character which may be readily and cheaply constructed, ywhich will he durable and efficient in service and a general improvement in the art.

These and other objects I attain by the con:- struction shownin theaccoinpaioying1 drawings, wherein for the purppse of illustrationis shownla preferred embodiment `of my 1nvention and wherein i v Figure 1 is a vertical sectional view through a dumping body constructed in accordance with my invention illus tratiug the body in the dumping `position in solid lines and in the loading and transporting position in dotted lines; i T L Figure 2 i is a horizontal sectional view showing the operating mechanism in plan g Figure 3 is an enlarged section on the line le-3 of Figure 2; i t v Figure il is an enlarged sect-ion showing the latch mech aniiin` for retaining the body `iuloading position'. i

Referring nowmore particularlyto the drawings, tlieudumpiug body includesxa sub framefhaving longitudinally extending side members for attachn'ient to `the chassis frame of a vehicle. These side frames are connected forwardly by i a transversely cxtending channel 11 which provides abumper or seat for the body when inloading' and transportingposition, as'will hereinafterbeJ come app arent.` Lon gitudinally spacedtransvei'sely extendingfi'ont andrear supports 12 and 13 connect the side members 10 adjacentthe center thereofand provide asupport for transversely spaced longitudinally extending 'operating mechanismsupports 14, l5 and 16.

The transversely extending supports 12,13 are preferably in the form of angle bars having horizontally disposed flanges abutting and `secured to the sidemeinbcrs 10 andthe mechanism supports lll, 15 and 16 are preferably likewise angle barshaving the flanges thereof bolted to the flanges of `the supports 12 and 13.

Mountedin the supports 14 and l5 are live shaftsl, 18, 19, and 21. The shaft 17 liltewiseextends through the support `16 and has an end thereof adapted for engagement with a crank whereby it may be rotated. Se curedto this shaftis `a pinion 22, which meshes with an idler pinion 23 mounted `upon ythe shaftlS. The shaft 19 is likewise exten-ded to pass throughthe mechanismsupe port 16 `and immediately outwardly of the supports 121 and 1G has secured. `thereto arms 24. Rotatably mounted upon the shaft isa gear; and pinion unit, of which the gear 25 meshes with the pinion23 of the shaft 18 and the pinion 26 meshes with the geai'i27 of a similar unit mounted upon the shaft 20. The pinion 28 ofthis unit meshes with a segment gear 29 having rigidly secured thereto a thrust arm 30) This segment gear 29 is rigide ly seciired to the shaft 21. y ,y i ,l l Likewise securedto the sliaft21 is a sector toothedscgment 3l havingteeth 32 arranged between short and longblaiilr faces 33 and 33t.` Mounted upon the shaft`20 .is a mutilated gear 3a having teeth 35 for enacting with the teeth" 32 of the gear 31 and a second set of teeth 36,

the purpose of which will presently appear.

` Between the teeth135 and 36, re-entrantly cui'vedfaces 37 and 381are provided for `co-` 1 action with the `curved faces 33 and i 33 of the segment 3l. y Thefteeth 36 mesh with the i teeth 39 of a mutilated gear 40. The gear 40 is fixed to the shaft 19, and it will be seen that as the shaft 21 is rotated to move the thrust arin 30 from a substantiallyhorizontal to a substantially vertical position, the intermittent gearing provided by the elements 31, 34 and 40wpermits first arise of the thrust arm unaccompanied by any movement of the shaft 19, as during this interval, the faces `33 and 37 of the elements 31 and 34 are in engagement. With this primary elevating movement of the arm completed, the teeth and 35 `of the elements 31an`d 34 come into 'i engagement, with the result that a further rise of the arm is accompanied by a rotation of theshaft 19. Rotation of the shaft 19 is suicient to cause movement thereof through an angle slightly greater than 180. lVhen the thrustv arm 30 is horizontally disposed and beforeoperation of the mutilatedl gear-` ing, the armsf24 are forwardly and down wardly inclined and when the movementof the mutilated gearing has beencompleted,

"thesearms are rearwardly and downwardly inclined. Operation of the mutilated gearing is completed -prior to the time thatthe thrust arm reaches its vertical position and subsequent movements of the thrust arm and of thev shaft 21 have no effect upon the positionv of the mutilated gearing, as during this time, thefaces 33*L and 38 of the elements 31 y and 34 areinengagement. `"While reference is made tohorizontal and vertical positions ofthe arm 30, it will be understoodthat this reference is made solely to differentiate the positions of this arm when the body is in oading or trans iorting position, and when the body is in dumping position, and that thesepositions need not be either actually` horizontal oriactually vertical! Attention is directed to the fact that engagement of the faces 33 and 37 or 33a and 33 serves to loci: the mutilated gear 34 against rotation and maintain the same in proper position foren-- gagement of the gear teeth 32 and This locking also serves to maintain the "arms 24 vagainst movement in either their forwardly y and downwardly inclined or forwardly and rearwardly'inclined positions.

t body41 is provided havingsecured therelto atransversely extending shaft 42. This body has further secured thereto Aadjacent each sidethereof and slightly in advance of the shaft42, bearings 43 monntingrollers 44 spaced-similarly to the 4side members 10` andV havingchannels 45 in their faces toreceive these side members and roll thereon as tracks. The side memberslO have secured thereto, im-

` mediatel `rearwarcilly of the `cross member A13, `inem ers-46 having at their vupper ends hooked terminals' which extend rearwardlyV and are "spaced above the members 10 a distance such that as the rollers 44l move forwardly thereover, their hubs or alvpo'rtion of the bearings 43 thereof engage `beneath these Vmembers 50 spaced suiliciently to admit the end of the thrust har 30 and receiving in the channels thereof rollers 51 carried by the ends of this thrust bar.4 At its `forward exs tremity, the body has a latch element 52 engaging with a enacting latch element 53 .car riedby the front cross member 11. The latch 53 is spring-pressed and automatically engages when the bodycomes to loading posi tion .and ma be disengaged through a cam lever 54. -Tlie shaft 42 has engagedthera with the rear ends of connecting rods 55, theforward endsof which are pivotally connected with the free ends of the :arms 24. The connection of the rods 55 with the shaft is held against longitudinal movement by suitable collars 56 and connecting rods 55 when the arms 24 are in their rearwardly and downwardly inclined positions, extend `into slots 57 formed in the support 13.

The operationiof my invention is as follows Assuming thebod andsub frame to be mounted upon a suita le vehicle and the body to be in the loading and transporting pisition with the latch 53 en aged, this latch is first disengaged and shaft 17 rotated. Ro-

tation of the shaft 17 throughthe gearing 22, 23, 25, 26, 27, 28 and 29 cases rotation of the shaft 21 and oscillation of the thrust arm 30. Movement of the thrust arm 3() causes the body 41 to tilt upon the axles of the rollers 44 as bearings, longitudinal movement of the body as a whole' being `at this time revented by the fact that the arms 24 arehe d against rotationV by engagement of the faces 33 and 37 of the intermitent gearing elements 31 and 34anilfurther by the fact that:the ends of these arms with which the connecting rods 55 are engaged are so vdisposed that a plane connecting said ends and the axis ofthe shaft 42 lies below the axis of theshaft 19 andthe ends of the arms are in advance thereof. When the forward end of the body has elevated sufficiently to permit clearance of the latch elements 52 and 53and of any other obstructions to rearward movement of the *i ly. During rearward travel of the body, the

rollers 44 operate upon the membersxlO and when this travel is limited by termination of the movement ofthe arms 24 and rods.-55,

bonasse continued movement of the thrust arm will cause a further pivotal movement of the body about the axes of the rollers. This movement causes the shaft 4t2 to engage in the grooves @t9 of the castings a8, which thenbecoine the pivotsfof the body about which the body rotates in response to further movements of the thrust arm. i i

`Attention is directed to the fact that the arms 2a and connecting rods `55 are at this time held against forward movement both by the engagementof the faces 38a and 38 and by the fact that the connection between the arms and connecting rods lies below a plane connecting the axe-s of the shafts 19 and ft2 and intermediate these shafts- Attention is further directed to the fact that as the arms arelieldagainst movement with relation to the shaft i2 and are at this time engagedin slots 5i" of the support lf3, no transverse movement of tliebody may take place during the `shiftfroin one pivot toaiiother, such as would permit the body Ato become misaligned with theside members l() and `prin/'ent proper reengageinent of the rollers therewith. Ifdesii-ed, the ljiodytl may be `provided witha thrust block 58 which, when the body is `in the loading and transporting position, engages against one of the arms 24 to insure against any possible movement of the same to a point where the resistance `provided by misalignnient of tho pivots would be removed to permit "rearward movement of the body.

lt will be obvious that tliense of the pivot blocks a8 merely serves to shift the pivotpoint of the body rearwardly, so that it will he more nearly at the center of gravity of the body when the dumping operation has been completed and that, if desired, these eXtra pivots n'iight be eliminated. It willalso'be obvious that by providing a construction wherein it is necessary that the body he first tilted to a certain degree before it canbe shifted longitudinally, the` use of a latchmay be resorted to which, without beingcompli- "cated, will very firmly loclthe body against movement. TWhere the body is capable initial longitudinal, aswell as tilting movement, the latch employed must, ofnccessity,

bel .more complicated. 4 llittention is directed to the fact that because of the construction `of the guide formed bythe channelmembers*50 and the engage- `nient ol the rollers 5l in the channels of this guide, it is impossible fonthebody to tilt to anentr-ssive degree under tlicinlluence of the load which would disturb tl i coniiectionbetween the body and thrust bar andnecessitate the return `of the body by hand. It also eu- `ables this thrust barto exercise an actual pull as well as 'the thrustin moving the body upon the frame. H i i Since the construction hcreinbefore set y forth is capable of a certain raugeof change "and modification without materially dep arting from the spirit ofthe inventioml do not limit myself to such specific structure eX- ccpt as hereinafter claimed.`
